2 Claims.

This invention relates to an improved nozzle or head for use inconnection with a machine for making wire cables and ropes and has forone of its objects the production of a simple and efficient means forguiding the strands to a proper position for twisting the strands into awire rope or cable.

Another object of this invention is the production of a simple andefficient means for facilitating the unreeling of the strands in theevent that the same should become irregularlyv twisted.

Other objects and advantages of the present invention will appearthroughout the following specication and claims.

In the drawing:

Figure 1 is a side elevational View of the head, a portion of the outersleeve being shown in section;

Figure 2 is a vertical sectional view taken on line 2-2 of Figure 1;

Figure 3 is a vertical sectional view taken on line 3-3 of Figure 1;

Figure 4 is a vertical sectional vie'w taken on line 4-4 of Figure 1,certain parts being shown in end elevation;

Figure 5 is a longitudinal sectional View of the head, certain partsbeing shown in elevation;

Figure 6 is a fragmentary perspective View of a portion of the Wireguiding head;

Figure l is a fragmentary top plan view of a modied type of head; and

Figure 8 is a fragmentary top plan view of a still further modied typeof head.

By referring to the drawing it will be seen that I0 designates the innersection of the head which comprises a tubular member over which fits theouter section II, this outer section II constituting a tubular member.The outer section II is preferably secured to the inner section I0 bymeans of `a set screw I2, as shown in detail in Figurefl. In this way,the inner and outer sections IB and II may be locked together and heldagainst independent rotation. The inner section IIJ of the head isprovided with an elongated longitudinally extending central bore I3, asshown in Figure 5, and this bore I3 is adapted to communicate with achannel formed in a machine upon which the head is adapted to be fitted.The section I0 may be secured in any suitable or desired manner to acollar I4 which may be carried by and secured in any desired way to themachine upon which the device is adapted to work, and this collar may beset or locked in position by means of a suitable set screw I5. Anysuitable or desired means may be employed for attaching the section I0of the head to the machine depending upon the nature of the machine uponwhich the head is adapted to be mounted.

The section ID is provided upon the periphery thereof with a pluralityof spaced longitudinally extending straight grooves I6 which areslightly undercut to retain the wires I'I within the grooves while thedevice is being assembled or while the wires are being adjusted. Theouter section II is also provided with a plurality of straight spacedlongitudinally extending undercut grooves I8 for receiving the wires I9.These grooves I6 and I8 will constitute a guide for the wire strands I'Iand I9 and properly guide the strands longitudinally toward the outeredge of the head where they may be twisted into a cable or wire rope 2Dabout or around a central core wire 2l which passes through the bore I3.

As an additional precaution, I preferably provide an encasement sleeve22 which ts over and encases the outer section Il and is held inposition by means of a set screw 23. It should be understood that anysuitable number of sections may be employed without departing from thespirit of the invention to provide a rope or cable of the desired numberof layers of wires.

In addition to the sections I0 and II, I also provide a wire guidingdisc 24 which. is provided with a series of radially disposed enlargedguiding apertures 25 through which the Wires I'I and I9 pass, as shownin Figures 1 and 2. This guiding disc 24 may be secured to the innersection I9 by means of a suitable set screw 26 which passes through thecollar 21, the collar 21 fitting snugly over the shank of the sectionI0, as shown in Figure 1.

The disc 24 is preferably larger in diameter than the sections I0 and II, and this disc 24 receives the wires II and I9 and the wires thenconverge centrally toward the sections I0 and II where they are guidedlongitudinally of these sections Within the respective grooves I6 and I8toward the outer end of the head where these wiresr converge centrallytoward the coiled or twisted cable 2D where the wires II and I9 aretwisted about the central core wire 2 I.

While these grooves I6 and IB may be straight and extend parallellongitudinally of the sections IIJ and I I these grooves may be inclinedtoward the left as indicated by the numeral 28 in Figure 7, or they maybe inclined toward the right as indicated by the numeral 29 in Figure 8.

The present invention is especially valuable in producing Wire cable,wire rope, and the like, and

is especially advantageous should the Wire for any reason becomeinjured, improperly twisted, or should there be any reason requiringreel back necessitated by kinking in the ller Wire which would cause thefiller Wire to jump out and be wound upon the outside.

By means of the present device, the encasement sleeve 22 may be loosenedand moved outwardly over the nished strand and the inner section orsections may be pushed toward the machine freeing the inner and llerwires Where the Wires may be easily` pulled back on the spool in themachine. This device therefore greatly.:v

facilitates the reeling back of the y become necessary and avoids thenecessity of c utting off the wire and destroying improperly v- Woundportions. In this Way considerable savings will be effected in thestrand in the event of difficulty, and the reel back of the Wires mayvmeans for retaining the Wires Within thechannels, a guiding disc havinga plurality of guiding apertures arranged radially of the center of thedisc for supporting and guiding wires toward the grooves in the head,said grooves being undercut to facilitate the holding of the wiresWithin the grooves, the head comprising a plurality of sections, eachsection containing grooves'and the sections fitting one upon the other,and a retaining sleeve fitting over` the outer section.

2. A sectional nozzle for guidingwire strands during the formation ofWire rope, cable and the jlilge, comprising a head having longitudinallyex- Y tending spaced Wire strand-receiving channels upon the peripherythereof, a removable section carried by said head and overlying thechannels for retaining the strands Within the channels, locking pinsengaging the removable section and lhead for locking the removablesection against independent rotation upon the head, a guiding discplaced in the rear of the removable section yand* having means forguiding wires therethrough, the outer end of the head and removablesections being unobstructed Ito. permit' the removal of the removablesection forwardly' of the head to permit the head and removableA sectionto be taken apart thereby facilitating the repairing of broken strandsand access to the strands Within the channels formed in the head. i
